4 Claims.

This invention relates to devices for cutting tape or the like, which is wound upon spools, and more particularly to a combined tape holding spool and cutter in which the roll of tape is freely rotatable about the spool barrel.

One object of this invention is to provide a device of the above nature having a pivoted cutting blade which is adapted to move inwardly upon the tape in guideways as the roll reduces in diameter, and in which means is provided to prevent the cutting edge of the blade from swinging beyond the periphery of the spool.

A further object is to provide a device of the above nature having means to cause the edge of derlying layer of tape on the roll to facilitate the removal of the remaining tape from the roll.

A still further object is to provide a combined holder and tape cutter of the above nature, which will be simple in construction, inexpensive to manufacture, and eflicient in use.

With these and other objects in view there have been illustrated on the accompanying drawing several forms in which the invention may be conveniently embodied in practice.

In the drawing:

Fig. 1 is a perspective view of a combined tape holder and cutter embodying the features of this invention.

Fig. 2 is an end view of the same with oneside of the spool broken away to show the relative positions of the cutting blade and the tape which is wound upon the spool.

Fig. 3 is a side view of the same.

Fig. 4 is an enlarged fragmentary view similar to Fig. 2.

Fig. 5 is an enlarged top plan view of the tape cutting blade and the associated spool parts.

Fig 6 is a section on line 6-5 of Fig. 4.

Fig. '7 is a perspective view of the cutter member, per se.

Figs. 8 and 9 represent end views of 'a pair of modified forms of the invention, respectively.

The features of this invention are shown in the drawing as incorporated in the combined tape holder and cutter illustrated in Figs. 1 to '7, wherein the reference characters l0 and Il indicate the circular side plates of the spool, and the numeral l2 indicates the tubular hub extending between the end plates l0 and H and upon which. a roll of tape I8 is wound for free rotation thereon.

The tape cutter, which is generally indicated by the reference character I5, is arouate in shape and is disposed between the, spool end members the cut tape to be slightly raised from the un- 1 1936, Serial No. 67,620

l0 and H. The cutter I5 is slidable radially with respect to the spool, having ears or lugs l6 and I1 extending from the opposite sides thereof into radial guide slots l8 and I9 which are provided in the side plates in and II respectively.

The cutter I5 is provided with a cutting edge on its forward end, which edge is offset some what with respect to the roll of tape. An arm 2| formed as part of the cutter I5 extends rearwardly from the ears I6 and I1.

Ears or lugs 22 and 23 are provided, one on each of the peripheral beads of the end plates l0 and H, each ear 22 and 23 being herein shown as struck out from the material of the respective end plate Ill, II, overlying the blade I5 15 adjacent its cutting edge 20. By the provision of the ears I6 and I1 disposedrin the guide slots l8 and IS, the blade I5 is slidable in and out, and is rockable with respect to the tape. The movement of the blade I5 is, however, limited in its swinging movements about the ears l6 and I! as pivots by the arm 2| which strikes the tape i3 upon which the blade l5 rests. The lugs 22 and 23 also limit the swinging movement of the blade IS in a clockwise direction, as viewed in Figs. 2 and 4, beyond the peripheral beads of the spool side plates l0 and II.

The cutting edge 20 provided on the blade I! is formed by beveling the end of the blade from the topsurface to the edge thereof as at 24. Moreover, the cutting edge 20 is slightly spaced upwardly from the roll of tape, curving the end of the blade upwardly, forming a curved under surface 26, which causes the end of the tape left on the roll to be raised slightly for permitting the finger nail of a user to be readily inserted thereunder whenever it is desired to detach an additional length of said tape.

Operation When the cutter has been installed on a tape roll holder, as above described, theuser will grasp the spool in one hand, and place a finger of said hand upon the cutting blade l5, as indicated in dotted lines at 30 in Fig. 4. The desired length of tape will then be unwound from the spool by lifting and pulling the end of said tape with the fingers of the other hand. The tape will then be severed by pulling it rearwardly against the cutting edge 20 as indicated in dotted lines 60 at 3| in Fig. 4. A twisting pull upon the tape, while the blade is being pressed inwardly against the roll to hold it from rotating will cause the desired length of tape to be cut ofi. The end of the tape remaining on the roll after the desired '80 ed thereon,

2' length has been removed will be left slightly raised from the next layer of tape, as shown at 32 in Figs. 2 and 4.

Figs. 8 and 9 illustrate two modified forms of end plates 32a and 33 which may also be employed within the spirit and scope of the invention. In the end plate 32a of Fig. 8, the guide slot 34 for the ears l6 and ll of the cutter member is tangent to the central hub l2, instead of being radial, as in the first form.

In the end plate 33 of Fig. 9, the guide slot 35 besides being substantially tangential to the hub I2 is convex outwardly as shown.

While there have been disclosed in this specification several forms in which the invention may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosures but may be modified and embodied in various other forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent is:

1. In a tape holder and cutter, a spool having a pair of end plates, a hub portion connecting said plates and having a roll of tape rotatably mounta tape cutter member rockably mounted within said end plates and being adapted to rest upon the roll of tape, said cutter member having an ear extending from each side thereof,

- each of said end members having a radial guiding a. slot to receive one of said ears, and means extending inwardly from each end plate to prevent said cutter member from rocking beyond the periphery of said end plates.

-2. In a tape holder and cutter, a spool having 40 end plates, a hub connecting said end plates and having a roll of tape rotatably mounted thereon, a tape cutter member disposed between and rockablysecured to said end plates and being adapted to rest upon said roll of ta said cutter member having ears extending from each side thereof, said end'plates each having a radial guide slot to receive one of said ears, and means extending rearwardly from said cutter member to engagesaid roll oi. tape and limit the rocking movement of said cutter.

3. In a tape holder and cutter, a spool having end plates, a hub connecting said end plates and having a roll of tape rotatably mounted thereon, a tape cutter member disposed between and rockably secured to said end plates and being adapted to rest upon said roll of tape, said cutter member having ears extending from each side thereof, said end plates each having guide means to receive one of said ears, said guide means extending outwardly from said hub to the periphery of said end plates, and handle means extending rearwardly from said cutter member to engage said roll of tape and limit the rocking movement of said cutter.

4. In a tape holder and cutter, a spool having end plates, a hub connecting said end plates and having a roll of tape rotatably mounted thereon, a tape cutter member disposed between and rockably secured to said end plates and being adapted to rest upon said roll of tape, said cutter member having guide means extending from each side thereof, said end plates each having guide means to cooperate with the guide means on the sides of said cutterasaid end plate guide means extending outwardly from said hub to the periphery of said end plates and handle means extending rearwardly from said cutter member to engage said roll of tape and limit the rocking movement of said cutter.
